Be it known that. l', FREDERICK D. AffrnAUsE, a citizen of the United States, and a resident of the borough of' Bronx, in the city and State ol' New York, have invented new and useful ln'iprovements in ltecision Engines, of which the following is a specification. Y

The object of my invention is to provide Io certain improvements in the construction, form, and arrangement of the several parts of' a recision-cngine, whereby greatly-improved results may be obtained from its operation, the engine at the same time being capable ol reversal and whichis under perfeet control ol the operator.

This present invention is disclosed in connection with a recision-engine operated by steam.

2o A practical embodiment of my invention is represented in the accompanying drawings in which i l* igure 1 represents the engine in longitudinal central section. Fig. 2 is a transverse 2 5 section taken in the plane of the line A A of Fig. 1 looking in the direction of the arrows. Figs. 3 and 4 are transverse sections taken in the plane of the line B B of Fig. 1, looking in the direction of the arrows, with the parts in 3o the positions which they assume for driving the engine forward and reversing the same. Figs. 5 and 6 are transverse sections taken in the plane of the line C C of Fig. l looking in the direction of the arrows, the parts being 3 5 shown in the position which they assume for driving the engine forward and for reversing the same. Fig. 7 is a transverse section taken in the plaire of the'line D D of Fig. l

looking in the direction of the arrows. Fig.

4o 8 is a view ol the exhaust end ot' the machine with the driving-pulley removed. Fig. 9 is a longitudinal section taken in the plane of thel line IC l') ol' Fig. 2 looking in the direction oll the arrrws, the engine-casing being removed.

Fig. l() is a detail central longitudinal section through thc inlet-valve, its adjustable cutoil", andfithe means for operating the same. Fig. l1 is a detail sectional vicw showing the connection ol-` the piston with the ring-conlining disk and the connection ol the ringconiining disk with the reversing-disk, and Fig. 12 is a detail view ol' one ol` the pistonwings.

'lihe engine-shalt is denoted b y l, and it mittin f its rotary motion sueh, for instance, as a be t-pullcy 2.

'lhe engine-casing is composed of two hubs 3 and 4, end plates 5 and 6, and a cylindrical wall 7, in the present instance formed inte- 6o gral with the end plate 5 and held in snu engagement with the end plate 6 by tie-bolts 8. Bolts 9 and 10 are used for securing the hubs 3 and 4 to the end plates 5. A loose ring-11 is mounted within the casing and is supported by three antifriction-rollers 12 so that the ring is eccentric to the shaft 1. fhe manner of mounting these rollers will be hereinafter Full y described.

ery, is fixed to the shaiit 1 concentric with the inner wall of the easingand eccentric to the loose ring 11, with the periphery of the piston at its bottom in engagement with the inner wall of the ring op osite its support on the 7 5. bottom roller 12. @his piston 13 is provided with oppositely-arrange( piston-wings 14 15, fitted to slide radially 1n recesses 16 17. These wings are, furthermore,guided by rods 18, which pass through the shaft and into re- 8o ccsses 19 and 2() in the piston-wings. Springs 21 22 are interposed between the ends of these rods 18 and the bottoms of the recesses 19 and 2O for holding the outer ends of the piston-wines in engagement with the inner wall of theoose ring 11.

The loose ring 11 is held in position between end plates 23 24, fixed to the opposite ends of the piston. In the present instance one of these plates 24is provided with a 9o sleeve 25, wlnch surrounds the shaft 1, on which sleeve the piston is mounted.

'lhe piston-head 13 is provided with a pcripheral inlet-port 26, communicating with a longitudinal inlet-port 27 immediately to the 95 rear of the piston-wing 14 and a similar peripheral inlet-port 28 and longitudinal inlet'- port 29 immediatelyr to the rear'of the pistonwing l5. This piston-head is further provided with a peripheral exhaust-port 30 and 10o longitudinal exhaust-port 3l innnediately in front of the piston-wing 14 and a similar peripheral exhaust-port 32 and longitudinal exhaust-port 33 immediately in front of the. piston-,wing l5. rl`hc longitudinal ports 27 29 3l 253 all open through both ends of the piston I8 and end plates 23 24. Reversingdisks IH 35 are loosely mounted on the shal't l adjacent te thcend plates 23 24. 'lhe disks 55 may be provided with :my means lor trails- 34 35 are held in engagement with the end 11o A piston 13, havirnr a cylindrical periph- 7o A A. en A www... n. w-MAU, vm.t....,;f s. i 44.5.

plates 23 24 by locking-rings 36 37. The disk 34 at the inle/t endof the piston is driven in the one or the other direction by a pin 38, carried by the ,el d plate 23, which enters a curved slot in the said disk, so that the disk has a limitennrojzry movement with respect tothe said plate.

The disk 35 at the outlet side of the piston is rotated by the eiid plate 24 of the piston in the one or the other direction through a pin 40, carried by the disk, which enters a curved slot 41 in the end plate, so that. this disk also has a limited rotary movement with respect to the end plate. The disk 34isipro'- vided with two ports' 42 43 therethrough, which' are arranged to be brought into alinement with either one set o`f longitudinal ports 31 33 or the other set of longitudinal ports 27 29 of the piston, according to the direction in which the engine is to be driven. The other disk 85 is similarl provided with two ports 44 45 therethroug which are arranged to be brought into alinement with one set of longitudinal ports 31 33 or the other set of longitudinal ports 27 29, according to the direction in which the engine is to be driven. The inlet-valve 46 comprises a hub-port 47, loosely mounted on the shaft 1, a ring portion 48, on which the end plate 6 of the casingis fitted, and a web 49 intermediate the 'ends of the ring. A artition 50 connects the hub and ring on t e inner side of the valve. Oppositely-arranged ports 51 52-are provided in the valve-ring 48 on the inner side of the web 49 for o eningcommuncation from .the interior o the casing to the inner side of the valve.

The passa e of steam through the inletport 51 maygbe controlled'by a cut-off comprising an inner plate 53, located on the inner side of the web 49 between the hub and ring, an outer plate 54, and a connectinU-pin 55, which passes through an elongated slot 56, concentric with the shaft 1.

The outer plate 54 is provided with a hub 57, loosely mounted on the shaft 1, to which hub is secured a lever 58, which extends through a circumferentially-elon ated slot 59 between the hub 4 and end 4p ate 6 of the easing. This inlet-valve may be rocked from the outside for the purpose of reversing the disk 34 to reverse the direction of the engine, as follows: A rock-lever 60 is pivoted at 61 bv tween the hub 4 and the end plate 6 of the casing. It has acnrved inner arm 62, to ther free end of which is attached a link 63, which link is pivoted to the valve-ring 48.

The arm 62 of the lever is -curved so as to peiiiiit the valve to he rocked the reA uircd dist-alice without causing the arm to hit the shaft 1. The valve-ring 48 is provided on its periphery with two outwardly-extended pins 64 65, which are arranged to engage a pirr 66 on a cani 67, pivoted at 68 to the end plate et' the casing. The cam 67 when at thi.l lmits of its rocking movementsin engagement with its stops 69 70 is out of engagement with the disk 34. While the cam is being rocked from one position to the other its peri hery will be brought into snug contact with t e periphery of the disk 34, so that the disk will be rotated the required distance with res ect to its iston to permit the ports in the dis to be shi ed from one side to the other ol the pistonwings. In the present instance the disk is provided with a V-shaped groove 71, and the peri )heryof the cam is tapered, as shown at 72.

The outlet-valve comprises a huh 73, loosely mounted on the shaft 1, a ring 74, on which the end plate 5 of the casing is fitted, and a Web 75, connecting the hub and ring for part of the distance around, the valve leaving a long curved port 76, which'is at all times in communication with the ports of the .reversing-disk 35. An exhaust-port 77 extends through the ring 74 of the outlet-valve and is at all times in open communication with an exhaust-port -78 in the end plate 5 of the casing, which exhaust-port 78 o ens to the exterior of the casing. The out et-valve is further provided with an end plate 79 for preventing the` passage of the steam 'omthe interior of the valve to the exterior of the casin except through the ports 77 78.

he disk 35 is rocked with respect to the piston to shift its ports 44 and 45 tothe one or the other side of the piston-Wings, as follows: A rock-lever 80 is pivoted at 81 between the end plate 5 and the hub 3 o the casina. The inner curved arm of the rock-shaft is denoted by 82, and it is provided with a link 83,which in turn is connected to the end-plate 79 of the outlet-valve. is provided with two pins 84 85, which are arranged to engage a pin 86 4on a rocking cam 87, pivoted at 88 to t e end plate 5 ofthe cas- The ring 74 of the outlet-valve l ICD Vhen the cani 87 is at the limits of its i movements in enga ement withits stops 89 90, its periphery wil be out'of en agement with the disk 35. As the cam isro'ced from one limit of its movement to the other it will frictionally engage the disk 35 and rock it a Irc' sufficient distance to shift its ports from One of steam between the valvesv and end plates, ol the casing, l provide suitable packingriugs 96.

Each one of the three rollers which sup-- ports thtl piston-ring is :nonni ed within thi;

casing, as follows: 'lwo bases 97 98 are pro- SSP vided with uprights 9S) 100, between which the roller 12 is mounted on an axle .101. Antifriction-l)carings 102 103 are interposed between the roller 12 and the uprights 99 100. These two bases 97 JS are overlapped and secured together by suitable screws 104 105.

'lo yieldingly hold the roller against the periphery ol the piston-ring, l provide the bases 97 95S with depending lugs 1.06 1 07, which cnter sockets in plugs 108 109, screwed into the peripheral wall 7 of the casing. Springs 110 11.1 are interposed between the lugslOG 107 and the bottoms of the sockets in the plugs. By adjusting the plugs the roller 12 may be pressed against the periphery of the pistonwin to a greater or lesser extent to procure the est result.

Proceeding to describe the operation ol this engine, it will be understood that the ports in the reversing-disk 34 are closed to the admission of steam while passing the inner faces of the inlet-valve and the inner plate 53 of the cut-oli'. It will also be seen that the ports in the reversing-disk 35 are closed against exhaust while the ports are passing over the inner face of the segmental web 75 of the outlet-valve.

Referring to Fig. 2, when the parts are in the position shown therein the s ace to the left of the piston-wings is being fe( withsteam from the inlet through .the ports 26 27, the ports 32 33 being closed to exhaust by the segmental web 7 5 of the outlet-valve, as above described'. Steam is also just being admitted through the ports 28 29 into the space between the piston-wing 15 and the contact between the piston 13 and ring at the bottom of the piston. At the same time the space between the piston-wing 14 and the contactpoint between the piston and piston-ring is open to exhaust through the ports 30 31.

The amount of steam to be fed to the engine may be regulated by sliding the cut-off inlet-valve to a greater or lesser extent for regulating the amount of opening through the port 51 in the said valve.

When it is desired to reverse the engine, the lever is rocked in one direction to reverse the disk 34 and the lever 80 is rocked in the other direction to reverse the disk 35, so that the ports which were the inlet-ports will now be the exhaust-ports and the ports which were the exhaust-ports will now be the inletorts.
